1. TECHNICAL FIELD OF THE INVENTION

The present invention relates to a truss system, comprising: at least a first chord; at least a second chord wherein the chords are arranged substantially parallel, diverging, converging, or sloped with respect to each other; a truss brace comprises a first end and second end; and at least a plate comprises a plurality of plate edges, disposed between the truss braces, either in succession or alternating, communicating with the truss braces outer or inner wall surface.

2. BACKGROUND OF THE INVENTION

Building roof structure is built by different type material like wooden roof, concrete roof and steel roof. Nowadays, steel roof is very common to use for residential building and industrial building. Steel material has advantages compare to wood and concrete because of higher mechanical strength compare to wood. Steel can recycle as raw material to steel billet to produce new product. Steel roof can fabricate into different shape and size depends on application and aesthetic requirement. The steel roof fabrication and installation time is shorter compare to concrete roof. Steel roof structure generally has 2 types: rigid frame or truss. Roof rigid frame is fabricated using hot rolled section (eg. I-beam) or metal plate to cut and welded into desired size and shape. Roof truss can be fabricated using hot rolled section or cold rolled section like steel pipe, angle bar, c-channel, batten and etc.

This present invention is a new type of steel roof truss which has a) higher stiffness compare to traditional bolt joining truss, b) can customize to different shape and length, c) ease to installation, and d) flexible to transport/shipping.

The racking upright and bracing usually is used in storage purpose. This technology introduces the V, W, M, N and other variant shapes bracing together with reinforcement plate for roof truss and lattice truss purpose.

The top section is cold rolled section with profiled. The top section side is punched with hole for bolting the section to the W (or M) or N-shaped bracing. The bottom section side hole can be configured in single row or multiple rows. The bracing joint has multiple holes like 3 holes, 4 holes, etc. This is to strengthen the bracing joint area. The section top area is punched with hole at the area for the purlin or channel support or along the whole length.

The W (or M)-shaped bracing and N-shaped bracing are fabricated using cold rolled section either lip channel or hollow section. The lip channel arrangement in single or double to join together. Hollow section is usually square shaped or rectangular shaped. The lip channel arrangement in single or multiple to join together. The lip channel and hollow section is cut and arrange into desired W-shaped or N-shaped depends on the truss design. The bracing and bracing intersection is joined by reinforcement plate to form the a) W(or M)-shaped, b) N-shaped, c) multiple W(or M)-shaped, and d) W(or M) and N-shaped combination. The reinforcement plate is welded or coupled by connecting means at the joint space between the bracings. Or the reinforcement plate extends to cover until both of the bracing holes at the joint.

The truss shape flat truss (Warren type, Howe type), slopping truss (Warren type, Howe type), and Howe truss. The spacing between the reinforcement plates can install a bush/tube to avoid deformation at the profiled section. The W-shaped bracing and N-shaped bracing is tightening by connecting means such as bolt and nut, bolt and locknut, rivet, or a combination thereof.

The purlin support bracket is either bolted or welded to top section. Mainly the truss can arrange in horizontally or inclined with respect to the ground plane is known as roof truss or girder truss. Also the truss can arrange vertically with respect to the ground plane is known as lattice truss. The lattice truss function is like building column to support the roof structure and wall cladding installation.
